'rEMPER ATUBE-REGULATING- sys'rnm.

To alliwk om z't may concern Q Be itknown that I, Harris SHAUL Cox, a

citizen of the United States, and a resident of Anderson, in the countyof Madison and State of Indiana, have invented a certain new and usefulImprovement in Temperature-Re lating Systems, of which the following lsa specification."

My 'nvention is an improvement in temperature regulating systems, forradiators and the like, wherein shutters are arranged for preventing thewherein indicating mechanism is provided controlled by said controlmeans for indicating the temperatureof the Water. 7

In the drawings: Figure 1 is a rear View of a radiator provided with theimproved temperature regulating device;

Fig. 2 is a section on the line 22 of' Fig. 1;

Fig. 3 is an enlarged detail section through the temperature controlledmeans for the shutters;

Fig. 4 is an enlarged detail side view of a portion of the shutters andtheir operatin mechanism;

ig. 5 is a'perspective view of the control lever Fig. 6 is a frontview-of the indicator; Fig; 7 is a section on the line 7-'--7 of Fig. 6an i Fig. 8 is a sectional yiew of a modified form of controller.

The present embodiment of the invention is shown in connection with aradiator comprising an upper tank 1 and a lower tank 2 connected by theusual. pipes 3 upon which and radiating plates}: and-"cool the saidpipes and the plates and the water in the pipes. A closing mechanism forthe frame for preventingthe circulation of air, consists of a seriesofshutters 6 each of which is secured to a shaft/7 journaled in thesupporting bars 8 at the sides of the radiator assage of air past thecooling pipes, and w erein-temperature con- Specification of LettersPatent.

columns 5, and the ends of the shafts extend beyond the supporting bars8.

At one end, each shaft is provided with a I radial arm 9 having itsouter end forked, and a coil spring 10 is arranged between each arm andthe adjacent supporting bar 8, the spring acting normally to close theshutter. The arms 9 are similarly arranged with respect to the shuttersand the arms 11 of Temperature control mechanism is arranged within theupper tank 1 of the razdiator, and connected with the bar 13 foropeningthe shutters. This mechanism comprises a casing 14 arrangedwithin the tank and adapted to contain a fluid that is quickly expandedby heat. This casing has a cylindrical extension 15 passing outside ofthe tank. A flange is shown at 16 to engage the under surface of thetank, and a valve or piston 17 is mounted to move in the extension andto be moved inwardly and outwardly in the extension by the expansion andcontrac- 'tion.of the fluid in the casing. A rod 18 is connected withthis valve or piston, and the outer end of the rod is connected witha'lever 19 pivoted at 20 on the flange 16. This lever extends outwardlytoward the bar 13 and the outer end of said lever is provided with anangular arm 21 having a lateral pin 22 which engages within a slot orguide-way in the upper end of'the bar 13.

i It will be evident that when the fluid'in the casing 14 expands anddrives the lunger or valve outwardly, the arm 21 of t e lever 19 will bemoved downwardly carrying with it the operating bar 13 for the shutters,and all the shutters will be simultaneously moved into 0 en position,the extent'of the opening de'pen ing upon the expansion in the casing 14and the consequent extent of movement of the valve or plunger 17 Q Themechanism shown more particularlyin Figs; 6 and 7 is designed toindicate the amount of air'passing through theradiatonf' that is, passinthrough between the shut ters. The sai mechanism is arran' edi-gat anysuitable point and comprises a su aw:

- ment with a loop 36 connected to the lowertially cylindrical bearingcasing 24 that is mounted in an opening in the dashboard 25, forinstance, and a shaft 26 is journaled in this casing. The said shaft hasa radial arm 27 at one end which is connected by a link 28 to adepending lug 29 on the lever 19 at the junction of the arm 29therewith. The arrangement is such that When the lever is swung theshaft will be oscillated and the shaft extends into an indicator casing30 on the opposite face of the dashboard 25 from the link 28. Withinthis casing a'hand or pointer 31 is secured to the shaft, and this handcooperates with an arc-shaped scale 32 arranged within the casing behindan arcshaped opening having a transparent cover plate 33 which permitsthe scale and the hand or pointer to be inspected. The scale isgraduated to indicate the amount of air passing through the radiator.Means is also provided for opening the shutters manually,

the said means comprising an elbow lever 34 which is pivoted at thebottom of the radiator, and one of the arms of the elbow lever has alaterally extending pin 35 in engageend of the bar 13. A treadle, notshown, may be connected to the other arm of the lever, and it will beevident that when the lever 34 is operated in a direction'to move thebar 13 downwardly, the shutters will be opened against the resistance ofthe springs.

In Fig. 8 is shown a modified form of controlling means, the said meanscomprising a casing 37 having a tubular extension 38 at one face and aflexible diaphragm 39 is arranged transversely of the casing adjacent tothe extension. The casing is adapted to be filled with a fluid expandingand contracting readily with the temperature changes, and a stem 40 isconnected with the diaphragm at its center, the said stem beingconnected with a lever 19 corresponding to the lever 19.

The operation of the modified form of controller is precisely the sameas that of the construction shown in Figs. 1 to 5.

I claim In combination with an automobile radiator, vertical bars at thesides thereof, shafts journaled in said bars, arms at one end of theshafts having their outer ends forked and curved, a spring connectingeach arm with the adjacent bar, an operating bar having loops at itsends, pins projecting from the operating bar and engaging the curvedforked'ends of the said arms, a thermally controlled member engaging oneof the looped ends of the operating bar to open the shutters, a manuallyoperated member connected with the remaining looped end of the operatingbar to admit of the shutters being operated at will, and an indicatorcooperating with the thermally controlled member.
